Abstract (en)
A composite material is made from alumina short fibers embedded in a matrix of metal. The fiber volume proportion of the alumina short fibers is between approximately 5% and approximately 50%. The metal is an alloy consisting essentially of between approximately 2% and approximately 6% of copper, between approximately 0.5% and approximately 4% of magnesium, and remainder substantially aluminum. The fiber volume proportion of the alumina short fibers may more desirably be between approximately 5% and approximately 40%; the magnesium content of the aluminum alloy matrix metal may more desirably be between approximately 2% and approximately 4%; and desirably the fiber volume proportion of the alumina short fibers may be between approximately 5% and approximately 20%, when the copper content of the aluminum alloy matrix metal should desirably be between approximately 3% and approximately 6%; or alternatively desirably the fiber volume proportion of the alumina short fibers may be between approximately 30% and approximately 40%, when the copper content of the aluminum alloy matrix metal should desirably be between approximately 2% and approximately 5%.
